      Expression of sec8Scer\UAS.P\T.T:Ivir\HA1 under the control of Scer\GAL4nos.PG in homozygous female sec5E13 germline clones results in egg chamber development arresting between stages 7 and 9, such that these females lay no eggs. The oocyte nucleus migrates appropriately to the anterior end of the cell in the double mutant germlines at stage 7, but the oocyte fails to enlarge, remaining comparable in size to the nurse cells. Some disruption of the nurse cell membranes is seen, with some cells fused and the ring canals clustered together.
